CHARLES STEIDLE, OF HILLSBORO, MISSOURI.

MIXING-MACHINE.

' Specification of Letters Patent.

Patented Oct. 5, 1909.

Application filed May 4, 1909. Serial No. 493,863.

To all whom it may concern:

Be it known that I, CHARLES STEIDLE, a citizen of the United States of America, residing at Hillsboro, in the county of Jefferson and State of Missouri, have invented new and useful Improvements in Mixing- Machines, of which the following` is a speciiication.

This invention relates to mixing machines designed for the purpose of mixing together various kinds of dry granular materials, and one of the principal objects of the same is to provide a mixing machine in which provision is made for throwing the concrete, grain or other granular material fed Ato the machine upward and outward against the walls of the casing by means of pins secured to the face of a disk mounted to rotate in the casing.

Another object of the invention is to p'rovide simple, reliable and eiiicient means for mixing granular materials comprising a casing having a shaft mounted therein, said shaft carrying a disk provided with a series of pins and an agitator to prevent clogging, said shaft extending through the hopper or feed opening of the casing.

These and other objects may be attained by means of the construction illustrated in the accompanying drawings, in which,-

Figure l is a central vertical section of a mixing machine made in accordance with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a horizontal section of the same taken on the line immediately above the distributer disk.

Referring to the drawings, the numeral l designates the casing which may be of any desired size dependent upon the class of materials to be operated upon, and said casing may be made of either wood or metal. Extending into the top of the casing is a suitable feed hopper 2. A shaft 3 extends through the hopper, and the inner end of said shaft is mounted to rotate in a metal bearing a secured to a cross bar 5 supported inside the casing l. The bottom floor 6 of the casing is inclined and leads to a discharge opening 7 at one side of the casing, said opening being provided with a sliding door 8 mounted in guideways 9. Instead of the inclined ioor I may employ an ordinary hopper-like floor with a sliding door or closure. The shaft 3 above the casing is supported in a suit-able bracket l0 extending diagonally across the top of the casing and provided with feet 1l secured to the top of the casing. Mounted on the shaft 3 is a belt pulley l2. Connected to the shaft 3 inside the casing is an agitator 13 provided with oppositely disposed blades or paddles la. The purpose of this agitator is to break up lumpy materials and to permit the same to drop upon the distributer disk.

Ihe distributer disk l5 comprises an outer raised rim 16 provided with a series of pins or spikes 17 projecting upward therefrom, and crossed bars 18 also provided with similar pins or projecting spikes 18a. This distributer disk has connected to its lower side a face plate 2O secured to the shaft 3 by means of a pin 2l extending through the hub of the face plate and through the shaft. rllhe distributer disk l5 is located a slight distance below the agitator 13.

The operation of the invention may be briefly described as follows The shaft 3 is rotated at any required speed by means of a belt extending around the pulley 12`from any suitable source of power. If it is desired to mix a concrete material, the cement, the sand and other materials are fed into the hopper 2 and are operated upon by the agitator and the distributer disk. The pins 17 and 18a break up the materials and discharge them outward by centrifugal action around the outer sides of the disk, and they drop upon the floor 6 and are discharged through t-he opening 7.

It will be obvious that a mixer made in accordance with my invention may be utilized for mixing all kinds of granular materials.

I claim A mixing machine comprising a casing having a feed hopper at the upper side thereof, a shaft extending through the hopper and j ournaled in a cross bar in the casing and in a bracket on top of the casing, a disk carried by the shaft, said disk having an upwardly projecting outer rim and crossed bms, a Series of metal pins o1' Spikes In testimony whereof I affix my Signature 1n presence of two wltnesses.

CHARLES STEIDLE.
